Circuit Schematic Low Ripple Regulated Power Supply using Transistor

PowerSupply. - Here is Circuit Schematic Low Ripple Regulated Power Supply using Transistor. This circuit like in figure 1 may be used where a high current is required with a low ripple voltage (such as in a high powered class AB amplifier when high quality reproduction is necessary ).
